Description

Dummy cable automatic welding device and welding method

The present invention is to position the ends of the dummy cables A, B, and C to the cable feeding part in the cable rewinding part equipped with the dummy cables A, B, and C respectively wound on the bobbin, then the dummy cable A of the X-axis transfer robot, After stacking B and C overlappingly, it is bitten by the gripper of the X-axis transfer robot, and then the X-axis transfer robot is operated in the forward and backward directions to place the ends of the dummy cables A, B, and C in the ultrasonic welding part, and then the dummy cable C is stopped. After rewinding the dummy cable B and the dummy cable C sequentially in the cable rewinding part, spread it out to the same length as the dummy cable C, stop it, and then fuse one end at the ultrasonic welding part, and then operate the X-axis transfer robot. After moving the dummy cables A, B, and C fused by the press punching part to the press punching part, press and punch a part of the part adjacent to the fusion part in the dummy cables A, B, C, and then the dummy by the operation of the X-axis transfer robot. After moving to the cable A, B, and C vision inspection part, the vision camera checks whether there is any abnormality in the fusion part, and then moves the dummy cables A, B, and C to the cutting part by the X-axis transfer robot to remove the part adjacent to the fusion part. When cutting, with both ends engaged with the ultrasonic welding part and the cutting part, the Y-axis transport unit of the cable transport part moves downward to the upper surface of the cut dummy cable A, vacuum-sucks it, pulls it upward, and hangs the dummy cable on the fork of the hanger unit It relates to an automatic dummy cable welding device, characterized in that the series of loading processes is performed as an automated process.

In general, the dummy cable is mainly used for isolating and protecting the actual cable.

On the other hand, since the cable installed to control the airbag mounted on the steering wheel of the driver's seat is inserted and installed inside the steering wheel, a cable capable of turning is mainly used.

The shape of the cable capable of turning is formed in a planar shape, and since winding and unwinding are repeated in the process of rotating the handle in the wound state, disconnection occurs due to abrasion due to contact between the turning cables, which causes a failure, and the lifespan is short. There is a problem of losing.

Therefore, in order to solve the above problems, a dummy cable having the same shape as the actual cable is manufactured and placed between the actual cables to prevent the actual cable from being worn.

Most of the dummy cables are not composed of one sheet, but are stacked on top of each other, and then both ends are fused so as not to be separated to form one and used.

In order to manufacture the dummy cable, an operator cuts the dummy cable to a certain length, transports the cut dummy cable to an ultrasonic welding machine, stacks several sheets to be stacked as many as desired, and then stacks one side and the other side of the dummy cable in order. When moving, it is ultrasonically fused.

The fused dummy cable is completed by the operator transporting it to the loading space.

However, since the operator performs the above series of work processes by hand, each work process is complicated, the accuracy is low, and the defect occurrence rate is high, so there is a problem in that productivity is lowered.

Republic of Korea Patent Application No. 2015 - 0033291 "Device for improving isolation using a dummy cable"

The present invention for solving the above problems is to cut a plurality of dummy cables to the same length, stack them on top of each other, and then perform a series of processes as an automated process, rather than manually performing the process of fusing both ends. It aims to improve productivity by minimizing the occurrence of defects and shortening the work process.

As a means of solving the above problem, the present invention is to position the ends of the dummy cables A, B, and C to the cable feeding part in the cable rewinding part equipped with the dummy cables A, B, and C respectively wound on the bobbin, and then to the dummy of the robot. After stacking cables A, B, and C overlappingly and fixing them to the same length, operate the X-axis transfer robot in the forward and backward directions to place the ends of dummy cables A, B, and C in the ultrasonic fusion zone, then stop the dummy cable C , In the cable rewinding part, sequentially rewind the dummy cable B and the dummy cable A, spread it out to the same length as the dummy cable C, stop it, and then fusion at the ultrasonic welding part, and then the dummy fused by the operation of the X-axis transfer robot. After moving the cables A, B, and C to the press punching part, press and punch some of the parts adjacent to the fusion part in the dummy cables A, B, and C, and then the dummy cables A, B by the operation of the X-axis transfer robot. , C is transferred to the vision inspection unit, and the reference point is checked by the vision camera, and then the dummy cables A, B, and C are moved to the cutting unit by the X-axis transfer robot to cut the part adjacent to the fusion site. With both ends engaged with the fusion part and the cutting part, the Y-axis transport unit of the cable transport part moves down to the upper surface of the cut dummy cable A, vacuum-sucks it, and pulls it upwards to attach the dummy cables A, B, It provides an automatic welding device for dummy cables characterized by a process of hanging and loading C sets.

As described above, the automatic dummy cable welding device of the present invention stacks a plurality of dummy cables on top of each other and then proceeds with a series of processes of cutting, ultrasonic welding, inspection and loading as an automated process to minimize defects and shorten the work process. It has the effect of improving productivity.
